description

These

universal,

monolithic,

9-bit

parity

generators/checkers

feature

odd

and

even

outputs to facilitate operation of either an odd or

even

parity

application.

capability is easily expanded by cascading.

The 54ACT11280 is characterized for operation

over the full military temperature range of − 55

°C

to 125

°C. The 74ACT11280 is characterized for
